Psi always respected in Linux-world: simple, free, stable, fast.
I follow its development for over a year. He recently updated. So what is it attracts me?
PSI has a minimalistic but very elegant interface and is perhaps the most advanced capabilities in network communication Jabber. A lot of amenities. This support avatars, and vCard contacts easily and conveniently connect and configure the server transports, through which communicate, group chat, support for multiple accounts, file transfer, multi-lingual and cross-platform.
Present branded chips, such as automatic selection of certain words in a different color (you can create a glossary of certain words and make them the color of the individual, for example, red). It is possible to encrypt via OpenPGP. Now the interface PSI supports Qt4 libraries (> = 4.2.3) and return QCA2 Qt3 and QCA1, of which he became even more beautiful. Change icons and emoticons, fonts, automatic spell checking, open source. Pleased profile settings, especially the hot keys, customizable on all major client opportunities.
Excellent client jabber-talkers. The latest version for Windows, Linux and MacOS is here.
